Abstract

Many wavefront sensors have been developed over the years, but most are not well suited for the photon-limited regime of coronagraphs designed for 10^-9 contrast ratios and small inner working angles (IWAs). To meet current coronagraphs low-order wavefront sensing requirements, it is essential to have a method that offers high sensitivity and preferably a linear response. We propose an innovative low-order wavefront sensor (LOWFS) design that is both achromatic and near free of non-common path aberrations (NCPAs).
